Iji na CRT image bụ na ihuenyo, na-ege ntị nwee ike ịnụ ụtọ ọkacha mmasị gị na-agbasa ozi, a ga-eziga ka elektrọn doo, looped ya dum ebe. Ụkpụrụ nke ime ihe nke ileba anya ma ọ bụ na TV, na nke a ngosi mmewere bụ a cathode ray tube, bụ mfe na-ewetara ihe atụ nke a nwa ọcha na ngwaọrụ.

N'ihi ya, ihe oyiyi na ihuenyo a kpụrụ site nanị n'otu isi ihe, na a elu ugboro nke na-agbaba gburugburu ọtụtụ narị ahịrị. The n'ozuzu picture anyị nwere ike ịhụ ya n'ihi inertia nke ahụ anyị.

Ke adianade do, image na-ike, na-achọ a mgbanwe nke pesonel. The elektrọn doo agba akara site na akara si n'elu na ala na azụ ọzọ n'ihi na ọ na chụpụrụ site ndọta N'ịbụ coils nke nupụsịrị usoro. Iji nke a bụ otú ahụ, ọ dị mkpa ịgbanwe na ugbu a na a na-mgbe nile.

Classical TV circuit agụnye dị iche components: ike akara na etiti ịgụ isiokwu, ọwa redio, akara unit, ike ala ugboro chrominance modul ma ọ bụrụ na a na agba-erite. The isi mmewere nke kwụ ịgụ isiokwu akara unit bụ a transformer. Na oge a na TV na ya na-emekarị jikọtara na a voltaji multiplier. Nzube ya - inye sawtooth pulses nke eletrik, nke na-ọnọ na nupụsịrị eriri igwe usoro. Multiplier voltaji, n'ịnyịnya na otu ụlọ dị ka akara transformer, na-arụpụta a elu, ruo 27 kilovolts ngwa ngwa voltaji na-enye osooso nke electrons na ha ije na ihuenyo nkpuchi, na ntekwasa phosphor. Ọ na-eme ka nri na picture tube site elu-voltaji gwara mmanụ na-abanye na-akpọ "ntụpọ" ichebe kọntaktị na mmebi nke ụlọ.

Transformer kwụ n'ịnyịnya ọnụ a multiplier (TDKS) nwere ọtụtụ windings akpụ ndị ọzọ akara n'ókè. A na-agụnye mgbanwe na-elekwasị anya na ịdị ukwuu nke osooso voltaji, na eriri igwe blanking blanking ihuenyo nke ekwesịghị anya.

N'ihi ya, abụọ iche iche nke windings nke deflecting usoro na-enye a raster iṅomi ekwesị (Ọrụ Nchịkwa, ČR) na ịgbasapụ (kwụ, CP). Dị ka a n'ihi nke ya udi bụ nnọọ nso na square, ma ọ dịghị nnọọ imeri ya. A ndiiche na-mere site dị iche na anya na electrons aghaghị imeri on ụzọ nkpuchi. The nso ka ihu na ihuenyo, n'ihi ya, ọ bụ ihe, na CRT ewepụghị na ihuenyo na-ata ahụhụ site na nke a ntụpọ ka ukwuu karịa ha "a ma ama" ogbo. Line transformer na njikọ na a multiplier na nupụsịrị usoro ndị a akpachara anya akara na ukpụhọde ihe, mgbe nke ahụ distortion na-aghọ ndị kacha nta.

TDKS ka àgwà a chọrọ dị nnọọ elu, oge nke ziri ezi na ime ihe nke dum telivishọn erite na-adabere na ya. Voltaji nkesa na-wuru n'ụdị a n'ite nzukọ a na-apụghị rụziri, ka ndị nile esịtidem kọntaktị n'etiti ndị windings ga-abụ nnọọ pụrụ ịdabere na.

Dị ka ọ bụla inductive ngwaọrụ, akara transformer nwere a magnetik isi na-eje ozi dị ka ndị isi nke coils na-etinye. Iji belata size, ọ na-mere si pụrụ iche ferrite na elu magnetik conductivity.

N'ihi na ihe niile ihe ndị a TDKS - ndị kasị oké ọnụ nnọchi nsọpụrụ mgbe CRT, mkpa nke pụrụ ibilite mgbe TV rụziri.
